Thanks Ates, Roman.

Russ, I was building another model for Open Scale rather than the Chippie....  Smiley It wasn't a super scale model either but I fancied a go. I might get it done yet, we'll see.

Trust me to get the wrong end of the stick Jon  Roll Eyes

Is this a 'secret' project ... most of the models that I actually finish are ones that I don't post about!
I don't think it has to be super scale .... as long as it's something that gives you a fighting chance if the flying is a success.

Hi Russ, nothing secret, just my little Chilton dimer. It won't have ANY chance but I thought it would be fun to have a go. It's not impossible that I'll finish it but we'll see...

(Apologies for the picture quality, I'm having to use an old phone camera at the moment...)

That's a nice design Jon, Mine flew very nicely outdoors. It's since gone to the big balsa pile in the sky after suffering multiple crunches on the large, but often branch strewn field near our house....

Andrew, yes it's the same one - Clive Gambles design from Mike's site. I've made a few mods, aiming for a bit more strength and durability than ultimate light weight. One problem is the limited prop clearance for ROG indoors although it should still be ok for a qualifying flight.

I used a 5" Guillows prop and 1/8" rubber if that info is any use for you.......

Thanks Andrew, I think I might need even smaller than that for ROG. I did measure but can't remember  Undecided

An original version of this kit just went for £50 on eBay.....

There was also a Cessna from the same series that went for £107!

You are probably taking the better route Jon.
I've gone down the 'get a decent static score first and then cross fingers for flying' route whereas the flying first route would probably be more satisfying.
Go for it! .... there's still a month or so to go.

Well the Chippie is nearly ready to cover. Only a week before trimming  Shocked
This lot weighs 16g, but there's sanding sealer and covering to add.

I understand that John O'Donnell is writing a piece on props, with some advice on small diameter/large blade area for scale models, for Aeromodeller.

Sometimes I wonder if a project that's done the right way, like this one's been done.....
I wonder if if maybe it tells us when it's done, not us telling it.

It's very clean and precise.
In other words....It has your name written all over it. Smiley

Cheers.

This one has been screaming "stop faffing about and cover me" for a while now...

I've been following your build, but I'd like to know your method of making wheels?

Sorry if your going over old ground.

Thanks chaps.

JBP - the wheels are based on Mike Stuart's method here:
http://www.ffscale.co.uk/comp9.htm

But with aluminium hubs.
http://www.rcgroups.com/forums/showpost.php?p=20892824&postcount=17

I've also found that using sanding sealer and then polishing them on the drill gives them a nice finish.

Do check the aluminium tube fits the wire you want to use! I made the wheels for this model over a year ago and when I went back to it I realised that they fitted some metric wire I no longer had enough of. 22 swg was too thin and springy for the UC and 20 swg was too thick for the hub. So I ended up removing some material from the ends of the 20 swg with wet and dry (laborious!)

Thanks Yak52,

I have some ugly black plastic wheels for my West Wings Piper Cub, always hated them.

The main issue with plastic wheels for me is the weight. The 1" wheels on this model weigh 0.4g each before painting.

At this rate I'll be adding details and lettering after trimming  Roll Eyes
